RMS minus ripple current , that is alternating current (sinusoidal wave form )it is including ripple voltage and ripple current . peak current is maximum peak in sinusoidal wave form . general used in choke (filter ) design calculation .AnswerHow do you compare the 'speed' of a circular saw with that of a reciprocating saw? One spins, while the other goes up and down. The answer is that you compare them, not in terms of their individual speeds, but in terms of their 'cutting speeds' (i.e. how fast they cut board).We do the same thing with a.c. and d.c. We compare one with the other in terms of the 'work' they do. So, for example, a 10-A (r.m.s.) a.c current will do precisely the same amount of work as a 10-A d.c. current.So the r.m.s. value of an a.c. current is exactly equivalent to the value of a d.c. current that will achieve the same amount of work. Because voltage is proportional to current, the r.m.s. value of an a.c. voltage and a d.c. voltage are also equivalent to each other.For a sinusoidal a.c. current or voltage, the r.m.s. value is 0.707 times the peak value.
John Garand was working at the Springfield Armory when he designed the automatic rifle that bears his name. Springfield Armory bid on an Army contract and produced them for the US Army. For Canada to purchase the rifle, it would have to have contracted with a foreign company which may not have been allowed by their policy. Some Canadians probably did use the Garand. The 1st Special Service Force (aka the Devil's Brigade) was an elite unit serving in Italy and South France, and it was composed of both US and Canadian soldiers. They also used the Johnson light machine gun (Johnny Gun), and the V42 dagger. In WW1 the Canadian Army used a rifle called the Ross, but it had problems, and they used the Lee-Enfield in WW2.
